Research Team


The research team of Choice OS is not a team comprised of academics with multiple degrees and PhDs. It is comprised of simple humans with varying degrees of education, simple humans with passion and undying intention to explore and discover what they have been told is undiscoverable. But then so were people such as Thomas Edison, arguably the greatest inventor and innovator of humanity, with offerings to humanity such as the light bulb, movies, the phonograph, the electrical distribution grid and more than a thousand other patents that have changed our lives who was mostly home schooled and did not even have a degree. The Wright brothers, inventors of the airplane didn’t even have a high school diploma and two of the greatest innovators of the twentieth century, Steve Jobs of Apple and Bill Gates of Microsoft were both college drop outs.

The research team operates out of Tierramitica (, a Happiness Research Center in a paradise situated in the high jungle of Peru near Tarapoto, San Martin, that started as an Ayahuasca Retreat center. An unlikely and controversial place for serious research into such crucial matters as depression, mental illness and the first ever Open Source Operating System for human beings, Choice OS. However, many famous and celebrated inventors, innovators and scientists have experimented with mind altering substances in an effort to liberate their perceptions, such as Sigmund Freud, the founder of psychoanalysis, who treated himself and patients with cocaine and even wrote a scientific paper about his findings, Steve Jobs or Francis Crick, who got a Nobel Prize as co-discoverer of the structure of DNA, who both experimented with LSD, to name a few. Although Tierramitica started as an Ayahuasca Retreat Center (because a lot of the initial breakthroughs into the clear view of the paradoxes in our belief systems were aided by the usage of Ayahuasca, a powerful psychotropic used for millennia  that has recently gained worldwide notoriety and recognition for its properties to combat depression, various mental disorders and serious addictions and is currently being researched scientifically in many scientific institutions worldwide), the center has phased out the use of the psychotropic, as research has centered into the contradictions in our belief systems as the principle culprit for most or all mental disorders.

Tierramitica used to offer the Mythic Voyage with the use of Ayahuasca, a heavy duty intensive transformational workshop, treating successfully disorders such as chronic depression, bipolarity, addiction, PTSD, lack of motivation, absence or numbness of feelings, suicidal tendencies, self-destructiveness, anger issues and every other kind of mental disorder. However, the Mythic Voyage graduated from principal usage of Ayahuasca to peripheral usage to zero usage with the introduction of Choice OS workshops that transform lives as testified by a multitude of enthusiastic reviews. Since Tierramitica is a totally self-funded research center, the offering of workshops not only ensures its financial survival, but also the availability of research subjects to further the research. Tierramitica phased out the use of Ayahuasca and is now dedicating itself to the Choice OS research, providing workshops that change lives and bring true and permanent happiness, self-love and enthusiasm for life through the discovery and eventual elimination of paradoxes in patients’ belief systems. Tierramitica is also actively supporting Visionary Art and provides cutting edge Art Therapy workshops.


The research team of Tierramitica and Choice OS is comprised of people who benefited from the Mythic Voyage and were blown away enough by the results to decide to dedicate their lives as unpaid volunteers to participate in the research and development of Choice OS and to further awareness into the causes of the greatest contemporary scourge of humanity, depression and associated mental disorders. They come from a wide variety of countries, cultural and social environments, professions and educational levels; some hold University degrees and other qualifications and experience on various fields, and some just come from the University of Life. All are passionate, inspired, open hearted human beings that do not accept that nothing can be done or that there are things that humans are incapable of comprehending. Human beings willing to commit the hubris of wanting to make sense of the world around us and the even greater hubris of being able to fully control who they are and how they feel, think, behave and function.

Mikis Hasson, born in Greece in 1960, is the founder of Tierramitica, the creator and principal guide of the Mythic Voyage and Choice OS, a philosopher and author of the books “A Mythic Voyage”, “Humanity: Genius or Crazy?” and “The Path to Homo Delectus”. After spending a life of trying to gain acceptance through successes in business, creating a family and various other achievements, his cozy life was demolished in 2002 through serious life threatening illness, divorce and financial collapse. After a period of deep, suicidal clinical depression he decided to live and dedicate some time to his growth, disengaged himself from his workaholic business interests and started a sabbatical to explore the world, both inside and outside.

To the surprise of his cynical, analytical mind he suspiciously encountered Shamanism through Dr. Alberto Villoldo and the Four Winds’ Light Body School, a program of workshops designed to teach and familiarize westerners to the wisdom and practices of indigenous Earth traditions and Shamanism in a palatable and understandable way. His sabbatical extended from one year to practically permanent and after completing the Light Body School started traveling extensively studying humanity, both with indigenous and contemporary shamans, sages and philosophers and through intensive study and experimentation on the human psyche and its influence on the totality of our being. In the process, he not only discovered a path to the most precious gift, happiness, but also valuable discoveries and insights on how humans work. In 2012 he founded Tierramitica as a Retreat Center, a Research Center and an experimental community in order to dedicate his life to his research and the development of tools and practices to help people that conventional and alternative therapies give up on. He is a genuinely, permanently happy man.

He is now the maintenance manager of the research center and more passionately convinced about his choices than ever before.

Jaclyn Wilchuck, born in Canada in 1988, studied Integrative Energy Healing and worked in the Service Industry. Always a seeker, she visited Tierramitica for a Mythic Voyage with her girlfriend Elizabeth in order to try to resolve relationship, identity and personal issues and was astounded to find answers to all of her questions in a paradox free belief system. They enthusiastically stayed on, their three year relationship finally becoming a healthy, loving relationship and after inspiring her mother and sister to attend a Mythic Voyage (her mother participating in the first ever Mythic Voyage without the use of Ayahuasca, the first direct application of Choice OS), she watched extraordinary transformations in both of them and is an ardent supporter and researcher of this new approach to combat depression and addiction.

Together with Jaclyn they have volunteered for the research team since early 2016 and are two of the youngest members of the experimental community, but also two of the most passionate and hard working.
